Mulch is a cover that will either absorb water or let it through, depending on the kind of mulch. A 2-inch layer of wood chips for instance will absorb only a little water and drain most of it. Sand absorbs a bit more, but also lets most of it through.
Neither will drain any water if they are not connected to a drainage system of pipes to evacuate the water. It will stay stagnant otherwise.
A common material used for drainage systems is a bed of gravel, with porous pipes at a slight inclination onto it, and more gravel put on the sides and top of the pipes.
The pipes themselves are usually clothed with some cheap recycled fabric to prevent the dirt from blocking the drainage holes in the pipes.
If you do not have a drainage system and simply want to know what material will absorb the most water to prevent most rain floodings, you can use a mulch of peat moss, or even better, incorporate it into the top soil. It absorbs several times its weight in water. It is a bit acidic though, so don't forget to add lime to reestablish the original acidity level of your soil.

Applying mulch around plants in the fall helps conserve soil by reducing moisture evaporation, thereby maintaining consistent soil hydration. It also insulates the soil, protecting plant roots from extreme temperature fluctuations. Additionally, mulch suppresses weed growth, which can compete for nutrients and water, and as it decomposes, it enriches the soil with organic matter. Overall, this practice promotes healthier plant growth and soil health.
The sucking noise is usually a good thing, it means that the drain is working properly, the noise comes from a swirl in the water that goes counter clockwise and pulls the water. That noise is actually air. joe jersey
Mixing topsoil and mulch can hinder the growth of plants because the mulch can create a barrier that prevents water and nutrients from reaching the soil. Additionally, mulch may decompose at different rates than topsoil, leading to uneven soil quality and structure over time. It’s generally more effective to use mulch as a surface cover to retain moisture and suppress weeds, rather than mixing it into the soil. Keeping them separate allows each to fulfill its role effectively.
topsoil
Topsoil is typically composed of a combination of mineral particles (like sand, silt, and clay), organic matter (such as decomposed plant and animal material), water, and air. The exact composition can vary depending on location and environmental factors.
Sandy topsoil is a type of soil that has a high proportion of sand particles. It drains quickly, so it can be prone to drought and erosion. However, it has good aeration and is easy to work with for gardening and landscaping.
Topsoil will sink because it is heavy. Topsoil is the top layer of soil and it extends downward from 2 to 12 inches.
The dirt or topsoil carried by running water is called sediment.
Waterbugs do not typically eat mulch; they are carnivorous insects that primarily feed on other insects and organic matter found in water. They are more likely to be found in aquatic environments where they hunt for prey. Mulch, being composed of decomposing plant material, does not provide the type of food they seek. However, other insects that may inhabit mulch could attract waterbugs if they are present nearby.
Sandy topsoil is said to be well-draining because water flows easily through the large spaces between the sand particles, allowing excess water to move downward quickly. This promotes good aeration and helps prevent waterlogging, making sandy soil suitable for certain plants but also requiring proper irrigation and fertility management.

A watershed is an area of land that drains to a common body of water.
A watershed is an area of land that drains to a common body of water.
The process is called leaching, where water transports nutrients and compounds from the topsoil to deeper layers, affecting the soil's composition and fertility.
